Removal of Cd2+ from aqueous solution using MgAICO3-layered double hydroxide / Nurul Izza Taib and Norzuyanti Mohd Aris

Anion clay hydrotalcite MgAlCO3 with a Mg/Al molar ratio of 3:1 was synthesized by co-precipitation at room temperature and pressure. The physicochemical properties were evaluated using Powder X-Ray Diffraction (PXRD), Fourier Transform Infrared (FTIR) spectroscopy and Thermogravimetric Analysis...
